Detailed Product Description

The ZX-212 flammable gas examination warning controller (hereafter refers to as controller) as the intelligence warning controller, it with has the explosion-proof performance SC610 combustible gas detector (to hereafter refer to as detector) to coordinate the use. The controller is being advantageous for the observation and the maintenance place of safety, the detector signal gives the controller through 485 main line way transmission, the controller may demonstrate the current channel number, conditions and so on channel density as well as warning or expiration. When the density value surpasses the warning predetermined value, the controller may send out the acousto-optic warning, and sends out the control signal, prompts the operators, thus avoids having each kind of safety incident.

The ZX-212 flammable gas warning controller widely uses in chemical, the petroleum, the metallurgy, the fuel depot, the liquid gas station, the painting work, the fuel gas losing matches and so on flammable gas to have, the storage, the use and so on indoor outside easy spillage risk place. the Z X-212 flammable gas warning controller's design, the manufacture conform to GB16808-1997 "Flammable gas Warning Controller Specification And Testing method" People's Republic of China national standards and corresponding regulations.
